CO2-to-Fuel : New Technology From Carbon Sciences
A handful of companies and scientists are finding ways to recycle CO2 and turn it back into gasoline and other transportation fuels.Carbon Sciences is furthest along in the CO2-to-fuels quest.In June, company chief technology officer Naveed Aslam figured out a way to break down CO2 at low temperature and pressure. His secret? Biocatalysts.
Although catalysts, such as enzymes and bacteria, can split CO2, they're very expensive, and typically must be replaced after every reaction. Aslam invented a polymer shell that protects them so they can be recycled. The same technology can extract hydrogen from water, avoiding the need for energy-intensive hydrolysis. The carbon and hydrogen are joined to form methanol, which can be refined into gasoline or jet fuel.
